IIRC some of the folks in the 2A community were relieved when the SCOTUS declined to review Maloney v. Cuomo. It was a weak case because (a) the Court could issue a narrow ruling that nunchaku weren't protected because they fail the "common use" test from Miller, or (b) the Court could rule that nunchaku were unprotected sporting goods rather than protected arms, essentially throwing out the case, and the pro-2A side would get nothing.
